\class SoBumpMapCoordinate SoBumpMapCoordinate.h Inventor/nodes/SoBumpMapCoordinate.h
\brief The SoBumpMapCoordinate class is a node for providing bump map coordinates to shape nodes.
\ingroup nodes
When encountering nodes of this type during traversal, the
coordinates it contains will be put on the state stack for later use
by shape nodes. The bump map coordinates can be used to specify
explicit coordinates for a bump map. The SoBumpMap node is used to
specify a bump map for the shape nodes.
Note that an SoBumpMapCoordinate node will \e replace the bump map
coordinates already present in the state (if any).
Also note that since the indexed shape nodes have no
bumpMapCoordIndex field, the textureCoordIndex field will be used
for selecting bump map coordinate indices. You can set the bump map
coordinate binding using the SoTextureCoordinateBinding node. Bump
map coordinates must therefore have the same binding as the texture
coordinates for texture unit 0.
If you supply no bump map coordinates for a shape, the texture
coordinates for texture unit 0 will be used.
